I have always found CCI Blazer ammo to be clean, and cheap. Of course some shooters take issue with the aluminum cases. Not me, just good cheap ammo that I don't have to pick up after ( non reloadable ).

stay away from the winclean. i purchased some from wall mart about a year ago for target practice and i couldn't even shoot the whole box. the barrel of my .45 became covered in this yellow dust/chalk like substance and the sound of the ignition of the powder even changed. I don't know id it was the lot or the wall mart but i think it was the brand I'll shoot winchester but not win"not so" clean.
